A passive component in a CDC-F network configuration is the MSH4-FSB Fiber Shuffle Module. This module is used to rearrange the fibers between the CDC-F modules and the wavelength routers, so that each wavelength router can access any of the 96 wavelengths in the C-band. The MSH4-FSB module does not require any power or active components, and it does not perform any optical amplification or switching2. References : Nokia Optical Diagnostics and Troubleshooting Course | Nokia, Nokia 1830 Photonic Service Switch (PSS) | Nokia

A “Power Adjustment Required” alarm is raised when the optical power levels of an amplifier are out of the expected range and need to be adjusted. To manually adjust the related amplifier optical power levels, the command config powermgmt ingress 1/10 adjust should be entered. This command will initiate a power adjustment process for the ingress amplifier in slot 1/10, which is the input port for the optical line signal. The command will also display the status and results of the power adjustment, such as success, failure, or conditional success. The other commands are incorrect because they either do not initiate a power adjustment process or have invalid syntax. References: Nokia Optical Diagnostics and Troubleshooting Course, OAM and Diagnostics Guide

On a bidirectional optical amplifier configuration, the Wavelength Tracker detection points are the LINE and SIG interfaces. The Wavelength Tracker is a feature that monitors the wavelength of each channel on the optical amplifier and provides feedback to the control system. The Wavelength Tracker can detect wavelength drifts, channel failures, or channel additions or removals on both directions of the optical amplifier. The LINE interface is the input/output port for the optical line signal, while the SIG interface is the input/output port for the optical signal from/to the transponder. The other options are incorrect because the LINEOUT and SIGOUT interfaces are not Wavelength Tracker detection points, and an optical amplifier has Wavelength Tracker detection points. References: Nokia Optical Diagnostics and Troubleshooting Course, OAM and Diagnostics Guide
